American Eagle Airlines Reserve Flight Attendant Vacation Slide

We the undersigned would like contract language in Section 10.G.3 of The 2012 Agreement Between The American Eagle Flight Attendants as represented by The Association of Flight Attendants-CWA, AFL-CIO reached on July 26, 2012, reviewed for discrepancies with regard to the "sliding rule" for Reserve vacation time. The current language states the following:
a. Slide the effective start date of the vacation up to four (4) days earlier in order to eliminate a block of Reserve availability that is scheduled immediately prior to her/his scheduled vacation block; or
b. Slide the effective start date of the vacation up to four (4) days later to eliminate a single block of reserve availability that is scheduled immediately after her/his scheduled vacation block.
c. Vacation slides will only be permitted to overlap into another contractual month, with the concurrence of Crew Scheduling.
As written, the current language does not specify that "a block of Reserve availability" can be broken up to accommodate a vacation slide, thereby resulting in lost "time off" at Crew Scheduling discretion. We do not concede to this outcome, and would like specific language to address this in the form of a side letter of agreement with American Eagle Airlines.
